hey Buff, here's the nVidia drivers from Omega... he tweaks them just for games. I've been using them on my ATI Radeon 9800Pro and have ntohing but good things to say about them! Just make sure you have your old drivers in case you decide to go back to them... (if nothing else you could redownload them from nVidia)

just click the nVidia link at the top then click on your OS...
assuming you are using XP (works on 98 too just a different way of getting there) one thing that really helps is making your page file static... what this means is when windows launches programs and runs out of memory it starts spooling unused things in memory to the harddrive (virtual memory if you will) until it is needed again. By default Windows changes the size of this file as needed on the fly. This slows you down as your hard drive is the slowest of your gaming components...
You can speed this up by setting one size for the drive so it is not changing while you are in the middle of a game slowing you down. Take the size of your RAM and multiply it x 1.5, in your case it comes out somewhere around 1100, I would go ahead and set your page file to 1.5 GB though just in case...
(In XP) Go to my computer, right click ond click on properties. Choose the Advanced tab, then choose advanced again... click on the performance button then advanced again, towards the bottom is the Virtual Memory settings. Click on change and a new window will appear.
You want to choose custom size, then in BOTH minimum and maximum boxes, put 1500. It will require you to restart your computer. I wouldn't do this unless you are a little comfortable changing things on your computer. The worst that would happen is when it tried to reboot it would freeze and tell you out fo virtual memory. You can reboot into safe mode and reset the page file from there.
Again, this is your call, if you aren't comfortable there are other things you can do to make it faster.

One would be before you start your game (unless you are playing online) turn off your virus protection, kill everything in your taskbar that is running (and not necessary) as well as control-alt-delete and go into task manager and kill apps processes uneccesary, things like printer monitors, quicken reminders etc... if it is essential to windows then it wont let you kill it. Look out for things that look like they are related to your nvidia, or joysticks etc... you dont wanna kill these! you can experiment and find the ones to kill, if it doesnt work when you go into your game, restart the PC and try again... no permanent harm is done from killing processes... >>>>>>>>>>>THEN go into the game.
I'll be back in a bit and list some more things to do... I have a list somewhere of different things that will speed your computer by freeing memory etc...
